Filter by:To investigate the relationship among the neural respiratory drive (NRD), the sensation of the dyspnea and the effect of the bronchodilator on each stage COPD patients.
There is a lack of effective treatments for chronic obstructive pulmonary disease (COPD) complicated with pulmonary hypertension. Previous studies have found that inhaled nitric oxide (iNO) can reduce pulmonary artery pressure and improve exercise capacity in COPD with pulmonary hypertension patients. However, the specific mechanism is unclear. The study aims to evaluate pulmonary ventilation/perfusion, pulmonary artery pressure, oxygenation, symptoms and quality of life in COPD with pulmonary hypertension patients after short-term treatment with iNO. Observing a series of pathophysiological changes caused by the treatment of pulmonary hypertension with iNO in COPD, the investigators hope to provide new theoretical basis and research ideas.
Menthol inhalation (MI) is a novel and promising treatment option for acute relief of dyspnea, however, the underlying ventilatory and/or neural related mechanisms for this relief in symptoms remain unknown. The overall aim of this research project is to systematically examine the mechanisms of dyspnea relief from MI in healthy individuals and those with COPD.
The goal of this type of study: clinical trial is to evaluate the effect of bronchial valve implantation on cardiac function and skeletal muscle function in Chronic Obstructive Pulmonary Disease. The main question it aims to answer are:evaluate the effect of bronchial valve implantation on cardiac function and skeletal muscle function. Participants will undergo Lung volume reduction surgery with endobronchial valve implantation.
People living with chronic obstructive pulmonary disease (COPD) may experience worsening of symptoms such as shortness of breath, cough and wheezing in addition to changes that may be expected for having COPD. The worsening of symptoms is called exacerbations or flare-ups and can be debilitating and frightening, requiring additional treatment, often with azithromycin. This is an antibiotic medicine that also has anti-inflammatory properties. It is prescribed as long-term prevention to reduce the risk of flare-ups. Some people may be affected by side effects from azithromycin. Antibiotic resistance is another concern, especially when using azithromycin for prevention rather than to treat active infection. It is currently unclear as to whether people should be advised to stop taking azithromycin once COPD has stabilised, or to stop it over the summer when fewer flare-ups happen. It is also not known if azithromycin is more effective in some people or more likely to cause side effects in others. Given these uncertainties, it is challenging to know how best to use azithromycin in managing COPD. Azithromycin is a valuable antibiotic, and should be prescribed where it has benefit but avoid unnecessary side effects and reduce the chances of bacteria becoming resistant to it. The purpose of this trial is to be able to gain results to answer these questions, and to establish the effects of stopping azithromycin in people whose COPD has stabilised, who have been taking it for at least 3 months. This trial will compare continuing azithromycin with stopping it completely, or stopping over the summer only, continuing over the winter. The investigators will compare the effects of these three treatments in the trial on flare-ups, symptoms and quality of life, and find out what factors may affect how individual participants respond to them.
This prospective randomized multicentered clinical study aims at implementing early diagnosis of lung cancer in high-risk heavy smokers in the Italian population. The main goal of the study is to develop a nationwide lung cancer prevention screening with high quality standard, similar to that of other screening programs i.e. breast, colon and cervix ongoing in Italy. The Italian Pulmonary Screening Network (RISP) includes 18 centers, which will promote primary prevention by offering a smoking cessation program (i.e. counselling and anti-smoking cytisine-based therapy) and secondary prevention by screening volunteers with chest Low Dose Computed Tomography (LDCT). The primary objective of the study is to demonstrate the non-inferiority of a risk-based screening strategy (less intensive, every 2 years) compared to the standard annual screening, in terms of stage I/II lung cancer incidence. Furthermore, the study aims to provide evidence whether blood biomarkers screening intervals can improve the efficiency of lung cancer screening by requiring less CT examinations while retaining the ability to diagnose lung cancer at curative state.
Scientific Rationale: In late 2019 and early 2020, researchers at the Wuhan Institute of Virology identified a potential new etiologic agent, called new coronavirus 2019 (nCoV-2019). Subsequently, the epidemic unleashed by this virus involved the whole world and radically changed the habits of the entire global population. Since that time, in fact, the need to contain the spread of infection through specific social distancing procedures and through the use of personal protective equipment has become compelling. The main tool was the requirement for all citizens to wear masks for airway protection. This measure has thus become in daily use for the majority of the population. Therefore, it has become increasingly important to evaluate the impact of mask wearing on activities of daily living (ADls), both in healthy subjects, for which several evidences have already been brought, and in patients with different diseases, for which data are still insufficient to fully describe the effects. Oxygen consumption and dyspnea during simple activities of daily living (ADLs) have already been studied in patients with heart failure (HF) and chronic obstructive pulmonary disease (COPD), and there is evidence that these subjects compared with healthy subjects perform ADLs at a higher percentage of their peak VO2 with more dyspnea. However, there are still no studies highlighting, however, the consequences of performing such activities while wearing a protective filtering facepiece particles class 2 (FFP2) mask, to date considered the most suitable to preserve the most fragile subjects from infection. In this study, therefore, the investigators aim to asess the effects of these devices on the ability to perform ADLs by evaluating the exchanges of respiratory gases in the body during the performance of normal activities or during sleep in patients with HF or COPD compared with healthy subjects.
The purpose of this study is to evaluate the ability of the Bora Care remote monitoring solution to detect early acute exacerbations of Chronic Obstructive Pulmonary Disease (COPD).
The former aim of this study is to determine whether the arm swings change in patients with Chronic Obstructive Pulmonary Disease (COPD) according to healthy subjects. The latter purposes to investigate the correlation between balance parameters and arm swing, how to change arm swing according to severity of the disease, and to determine the relationship between balance and the severity of disease, the relationship of posture both arm swing and severity of disease in patients with COPD. In accordance with this purposes, 20 patients with COPD who have Global Initiative for Chronic Obstruction Lung Disease (GOLD) stage 1-2-3 and 20 healthy controls will be included between the ages of 40 and 65, respectively. Tests and questionnaires will be used in order to determine the severity of COPD and to evaluate posture. Berg Balance Scale, Time Up and Go Test, 6 Minute Pegboard and Ring Test, 6 Minute Walk Test and gait analysis will be performed. It is expected that by determining the parameters that can be affected by severity of COPD. It is estimate to have information about severity of the disease by means of observational analysis. It will guide professional working in the field.
The goal of this clinical trial is to learn whether semaglutide, an FDA-approved treatment for diabetes and obesity, is feasible and tolerable in patients with advanced lung disease. The main question[s] it aims to answer are: 1. Are patients with advanced lung disease able to tolerate semaglutide therapy? 2. Are we able to titrate semaglutide therapy to a target weight? Participants will be asked to perform pulmonary function, physical function and body composition testing, as well as a blood draw before and after 12-weeks of semaglutide therapy. While on therapy, subjects will be surveyed regarding any adverse events or side effects.
